Since the connecting plate 212, the hinged plate 2103 and the push plate 2104 are hinged, when the connecting plate 212 moves, the annular slider 218 can slide in the annular slide groove 217. At the same time, the movement of the connecting plate 212 can also push the push plate 2104 upward until the push plate 2104 drives the insert block 2105 to pass through the slot 2106, which can drive the furnace cover 5 to rise and the furnace cover 5 can be opened, so that it is convenient to directly inject a large amount of refining agent into the liquid aluminum insulation furnace body 1 in the later stage, which can reduce the feeding time.
